Description: Palifosfamide, also known as ZIO201, is a synthetic mustard compound with potential antineoplastic activity. An active metabolite of ifosfamide covalently linked to the amino acid lysine for stability, palifosfamide irreversibly alkylates and cross-links DNA through GC base pairs, resulting in irreparable 7-atom inter-strand cross-links; inhibition of DNA replication and cell death follow. Unlike ifosfamide, this agent is not metabolized to acrolein or chloroacetaldehyde, metabolites associated with bladder and CNS toxicities. In addition, because palifosfamide does not require activation by aldehyde dehydrogenase, it may overcome the tumor resistance seen with ifosfamide.

Palifosfamide (ZIO-201) is currently developed by ZIOPHARM Oncology, Inc. It is a proprietary stabilized metabolite of ifosfamide. Ifosfamide has been shown to be effective in high doses in treating testicular cancer, sarcoma and lymphoma. Ifosfamide-based treatment generally represents the standard of care for sarcoma; however, it is not approved by the FDA in this indication. Ifosfamide metabolites include acrolein and chloroacetaldehyde, both highly toxic. Preclinical studies have shown that palifosfamide has activity in leukemia and solid tumor cancers. These studies also indicate that palifosfamide has a better safety profile than ifosfamide, likely because the toxic metabolites of ifosfamide, acrolein and chloroacetaldehyde are not present in palifosfamide. We believe the administration of palifosfamide may avoid many of the toxicities of ifosfamide without compromising the activity of the drug. see ZIOPHARM's website: http://www.ziopharm.com/clinical_zio201.php.
